Rough Guide to IETF 95: Scalability and Performance

Mat Ford
By Mat FordTechnology Program Manager

In this post I’ll highlight some of the Internet Engineering Task Force (IETF) and Internet Research Task Force (IRTF) groups meeting as part of the IETF 95 meeting in Buenos Aires next week. These groups are working to explore and address more sophisticated ways to use and share available bandwidth, improve Internet performance, and otherwise efficiently get Internet content to where it needs to be.

Measurement techniques and data sources that could help us to make better engineering decisions to work around some of the rigidity in the protocol stack will be the subject of the proposed Measurement and Analysis for Protocols (maprg) research group meeting on Monday morning. The agenda for the session includes a presentation on the results Apple have obtained from their use of beta software for wide-area measurements.

The Alternatives to Content Classification for Operator Resource Deployment (accord) BoF will take place on Thursday morning. Encryption poses a challenge for cellular networks that use communication metadata to categorise sessions by their service requirements. This BoF session will seek to educate attendees about the realities of cellular networks today, and explore whether there are ways to provide the signals these networks need in the presence of ubiquitous encryption. This meeting is a follow-up activity from the IAB MaRNEW workshop that took place last year.

On Tuesday, Applied Networking Research Prize winners Zakir Durumeric and Roya Ensafi will present their research results. Zakir will talk about a detailed study of email security and Roya will present her analysis of the Great Firewall of China.

Packet networks give rise to transient congestion by design and several groups are meeting to discuss different aspects of congestion control and avoidance. The RTP Media Congestion Avoidance Techniques working group is developing and evaluating congestion control algorithms to handle the emerging use of the Internet for real-time audio and video communication. The Internet Congestion Control research group (iccrg) will meet to discuss some of the latest innovations and thinking in relation to congestion control and managing congestion on the Internet.

For regulators, being able to monitor the performance of networks, and the extent to which congestion or other factors are impacting consumers’ experience of the network is very important. The lmap working group is meeting in Buenos Aires to advance their important work on standardizing a large-scale broadband performance measurement infrastructure.
